Specification of Letters Patent.

I0 all whom it may concern:

Be it known that I. LEDRU It. BENDER, a citizen of the United States,residing at Elizabethville, in the county of Dauphin and State ofPennsylvania, have invented certain new and useful Improvements inMiter-Boxes, of which the following is a specification.

My invention relates to miter boxes and more particularly to that classof miter boxes which includes swinging saw holders.

The object of my invention is to provide a cheap and simple articlewhich may be folded into compact form to occupy a minimum of spacewithin a tool chest or bag and which comprises means for correctlyadjusting its alinelnent, simple and compact means for locking theswinging saw frame in any selected position, means for adjusting saidsaw frame for the admission of blades of varying thicknesses, and meansfor adjusting and locking said frame in a selected angular position forcutting angle miter-s or for folding my improved device preparatory tostoring it away. 1

With these objects in view my invention consists in the followingfeatures of construction and arrangement hereinafter described andpointed out in the accompanying drawings, in which,

Figure 1. is a perspective view of my improved device. Fig. 2 is afragmentary perspective view, enlarged, and showing the means forlocking the saw frame in an angular position, Fig. 3 is an enlargedperspective view of the double cum locking nut. Fig. 4, is alongitudinal sectional through the device shown in Fig. 1. Fig. 5 is adetail sectional view showing more particularly the locking inc-ansshown in Fig. 2. Fig. 6 is a detail sectional view illustratingthe meansfor adjusting the holder for saws of different thicknesses, and, Fig. 7is a perspective view of a slightly modified form of holder detached.

In the practical embodiment of my invention I provide a foundation board1 provided with a strip 2 attached to its lower edge and at right anglesthereto in order to squarely and firmly seat the board 1 on any suitablesupport, openings 3 in said board being provided through which screws orother fastening means may be driven into support. On the board 1, Iarrange a metal base 4 pivot-ally connected thereto by a bolt 5 andprovided with transverse openings 6 through which screws 7 project fromsaid board 1. An adjusting screw 8 is mounted through a bracket 9attached to the board 1 and is adapted to be screwed into the lug 10attached to said base plate 4. Thus, said plate 4-may be adjusted to acorrect alinement when it is necessary. Pivot-ally mounted on the bolt 5above said base plate 4 is a swinging frame 11 having a rear flangedsegment 12 form ed thereon and provided with a plurality of notches 1.3in the flange thereof. A spring tongue 14 is attached at its rear end tothe base plate 4 and works in guiding lugs 15 also attached to said baseplate 1. The tongue 14 is adapted to project within any one of thenotches 13 in the segment 12 to lock the frame 11 immovable.

Projecting through the board 1, through a transverse slot (not shown) inthe base plate 4 and through the curved slot 16 in the frame 11 is astud 17 having arranged thereon one end of the locking plate 18connected at its other end about the bolt 5. Mounted on said stud abovesaid plate 18 is a nut 19 provided with a handle 20 and a pair of camshoulders 21 and 22, the cam 21., being the locking cam and the cam 22the releasing cam. Above the nut 19 the stud 17 is further provided witha transverse opening through which projects one end of the rod 23mounted at its other end on the bolt 5. Thus it will be seen byreference to Fig. 1. that when the nut 19 is turned in one direction thecam 22 engages beneath the end of the tongue 14 to lift the same freeand allow the frame 11 to be swung around. Further it will be seen thaton moving the nut 19 in the opposite direction the cam 21 will engagebeneath the rod 23 and come quently said nut will bear downwardly uponthe locking plate 18 to tightly lock the frame 11. By this means I amable to lock said frame 11 at any point, independent of the tongue 14and the notches 1.3.

Integrally united to and extending vertically from the frame 11 at thesides thereof are the ears 24 in the extremities of which is pivotallymounted the saw frame arranged to swing with said frame and capable ofangular movement with relation thereto by reason of its pivotalmounting. Said saw frame comprises spaced side members 25 united attheir upper ends and providing between themselves transverse slots 26through which a saw is to be reciprocated.

In the form illustrated in Fig. 7 I have shown a saw frame 27-constructed of bicycle or other light metal tubing slotted at 28 tocorrespond with the slots 26 of the form shown in Figs. 1 to 6. Witheither of these forms I may use blocks or shoes 29 to assist incorrectly guiding the saw. At one side of the saw frame and mounted onand depending from the bolt 30, by which said frame is pivoted to theears 24, is a locking plate 31, through the lower end of which isloosely mounted a locking screw 32 threaded through the ear 24. Thuswhen said screw is turned by means of a screw driver or a tool insertedthrough the open ing 33, the plate 31 will be drawn inward toward thecar 24 thus locking the saw frame at any angle. Thus the saw frame maybe moved to an angular position in order to cut an angle miter or it maybe folded upon the board 1 preparatory to storing the same away in achest or bag.

With reference to Fig. 6 I have shown an adjusting screw 34 threadedlyengaging through one of the side members 25 of the saw frame and bearingagainst the other side member in order that when said screw is turnedsaid side members will be forced apart to admit a saw blade of greaterthickness within the slot 26. It will be seen that although I have shownthe screw 34 applied to the form of saw frame shown in Figs. 1 to 6, itwill operate as well and may be readily applied to the form of frameshown in Fig. '7.

Having thus fully described my invention, 1 claim 1. In a miter box, thecombination of an adjustably mounted base plate, a swinging framemounted thereon and having a curved slot therein, a saw frame foldablymounted on said frame, an upstanding stud arranged through said slot, acam nut rotatively mounted on said stud, and a vertically stationaryelement carried by said stud and arranged to receive said camthereagainst to force said nut downward and lock said frame,substantially as described.

2. In a miter box, the combination of an a'djustably mounted base plate,a swinging frame mounted thereon having a curved slot therein andprovided with a notched segment, a locking tongue adapted to engagewithin said notches to lock said frame, a saw frame foldably mounted onsaid frame, an upstanding stud arranged through said slot, a doublecammed nut rotatively mounted on said stud, a vertically stationaryelement carried by said stud arranged to receive one of said camsthereagainst to force said nut downward and lock said frame, the otherof said cams being arranged to move beneath said locking tongue toremove the same from said segment.
